Description                                        

The TC1540 is a highly versatile 2-wire RS-485 fiber optic modem that can mix or match RS-232, RS-422 or RS-485 (2-wire or 4-wire) interfaces, as required.  For example, a user could have a 2-wire RS-485 interface on one end and an RS-232, RS-422 or 4-wire RS-485 interface on the other.  2-wire RS-485 versions can be converted to 4-wire RS-485 by simply changing a DIP switch.

The TC1540 supports asynchronous data rates up to 500 Kbps*, depending on the electrical interface, and is compatible with all popular types and sizes of multimode (850/1300nm) or single mode (1300/1550nm) fiber optic cable.  Distances up to 80km are possible.

Diagnostics include a built-in Test Signal Generator that verifies both device and fiber optic link operation. This feature benefits users by helping technicians verify that both local and remote devices and the fiber optic link are operating normally. Local and Remote Loopback Tests are available to verify electrical and fiber connections.

Eight DIP switches and seven LED indicators are provided to help installation and troubleshooting.  An extreme temperature version (-20°C to 70°C), Model TC1540T, is also available.

Fiber optic connectors are ST or FC.  Electrical connectors are terminal blocks.  Power is 12VDC at 250mA; optional 24VDC or 115/230VAC with an external power cube.
